Steve, a baseball fan who regularly goes to games right after work, is thirsty and hungry by the time he gets to the ballpark. He hopes and desires that the food and drink vendors will visit his section of the stands frequently. Another fan, Bart, who regularly has dinner elsewhere before he attends games, has a lower level of desired service from the food and drink vendors at the ballpark. In this example, Steve and Bart have different ________ that shape their desired level of service.
